Expo CLI

Expo CLI is a command line app that is the main interface between a developer and Expo tools. You'll use it for a variety of tasks, such as:
  • Creating new projects
  • Developing your app: running the project server, viewing logs, opening your app in a simulator
  • Publishing your app JavaScript and other assets and managing releasing them as updates
  • Building binaries (aab and ipa files) to be uploaded to the App Store and Play Store
  • Managing Apple Credentials and Google Keystores
You may use the CLI in your terminal or use the web based interface (it opens automatically by default, or you can press d from the CLI to open it on demand). The web interface enables you to use some of the most often used features from a quick-to-use graphical interface. We’ve only scratched the surface of what expo-cli can do so far. Be sure to check out all the possible commands below!

Installation

Terminal
→ npm install -g expo-cli

Run expo --version to determine what version you are currently working with.

The commands listed below are derived from the latest version of Expo CLI. You can view the list of commands available with your version in your terminal using expo --help. To learn more about a specific command and its options use expo [command] --help.
Terminal

  • Dev Tools UI has been deprecated in favor of the the CLI's Terminal UI, Flipper, and Remote Debugging.
  • npx expo install now supports installing the correct version of react-native, react, react-dom automatically.
  • Tooling now supports pnpm along with Yarn and npm, the default is still Yarn.
  • Dropped the deprecated --config argument across all commands. Use app.config.js instead.
  • No longer shipping adb in the CLI. Users must manually install adb to interact with connected Android devices.
  • Experimental $EXPO_USE_APPLE_DEVICE feature (expo run:ios -d) is now the default behavior. Global ios-deploy package is no longer required.
  • npx expo export works like expo export --experimental-bundle, i.e. exports for eas update and not expo publish. PR.
    • Dropped arguments: --public-url, --asset-url, --merge-src-url, --merge-src-dir, -t, --target, --experimental-bundle, --config, -q, --quiet
    • Dropped aliases for --dump-assetmap (-d) and --dump-sourcemap (-s).
    • Dropped warning about clearing dist folder that is shown between runs, this is akin to all other bundler commands across web tooling.
    • Dropped all merging code because experimental bundle does not support index files so we don't need to support merging index files.
    • Dropped the quiet flag as this appears to do nothing anymore.
  • Parts of expo upgrade and expo doctor have been merged into npx expo install via the --fix and --check flags. PR.
  • Dropped unused generated .exprc, .expo/packager-info.json files.
  • Dropped all deprecated support for *.expo.js files.
  • Reduced usage of .expo/settings.json to provide a more sandboxed state between processes.

  • Dropped $XDL_PORT, $XDL_HOST, $XDL_SCHEME, $SERVER_URL in favor of $EXPO_STAGING and $EXPO_LOCAL environment variables.
  • Dropped $EXPO_PACKAGER_HOSTNAME, $EXPO_MANIFEST_PROXY_URL environment variables.
  • Dropped $EXPO_EDITOR in favor of $EDITOR environment variable.
  • Utilize $DEBUG=expo:* more and $EXPO_DEBUG less (more control).
